2179a07c0c rockchip: rk3288: sdram: fix DDR address range
The all current Rockchip SoCs supporting 4GB of ram have problems
accessing the memory region 0xfe000000~0xff000000. Actually, some IP
controller can't address to, so let's limit the available range.

This patch fixes a bug which found in miniarm-rk3288-4GB board. The
U-Boot was relocated to 0xfef72000, and .bss variants was also
relocated, such as do_fat_read_at_block. Once eMMC controller transfer
data to do_fat_read_at_block via DMA, DMAC can't access more than
0xfe000000. So that DMAC didn't work sane.

c482c60a14 rockchip: sdram: Fix register layout for Linux
The ChromeOS kernel reads the RAM settings from PMU_SYS_REG2 and expects
the bootloader to store the necessary information there.  We're using
the same register to pass the same information between the SPL and
U-Boot but in a slightly different format.

Change this to use the format expected by the Linux DMC driver so that
the system doesn't hang in Linux by misconfiguring the RAM.

This is almost the same as commit b5788dc ("rockchip: rk3288: correct
sdram setting") which was reverted in commit b525556 ("Revert "rockchip:
rk3288: correct sdram setting"") but parenthese have been added to apply
the mask correctly when reading the "bw" setting and a couple of minor
style issues have been fixed to keep check_patch.pl happy.

c3aad6f65b rockchip: Use rockchip_get_clk() to obtain the SoC clock
The current code picks the first available clock. In U-Boot proper this is
the oscillator device, not the SoC clock device. As a result the HDMI display
does not work.

Fix this by calling rockchip_get_clk() instead.

086ec0e26d rockchip: sdram: Update the driver to support of-platdata
Add support for of-platdata with rk3288 SDRAM initr. This requires decoding
the of-platdata struct and setting up the device from that. Also the driver
needs to be renamed to match the string that of-platdata will search for.

The platform data is copied from the of-platdata structure to the one used
by the driver. This allows the same code to be used with device tree and
of-platdata.

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

1163625898 Rename reset to sysreset
The current reset API implements a method to reset the entire system.
In the near future, I'd like to introduce code that implements the device
tree reset bindings; i.e. the equivalent of the Linux kernel's reset API.
This controls resets to individual HW blocks or external chips with reset
signals. It doesn't make sense to merge the two APIs into one since they
have different semantic purposes. Resolve the naming conflict by renaming
the existing reset API to sysreset instead, so the new reset API can be
called just reset.

b5788dc0dd rockchip: rk3288: correct sdram setting
The DMC driver in v3.14 kernel[0] get the ddr setting from PMU_SYS_REG2,
and it expects uboot to store the value using a same protocol. But now
the ddr setting value is different with DMC, so if you enable the DMC,
system would crash in kernel. Correct the sdram setting here, according
to the requirements of kernel.
